How can PHP developers ensure proper character encoding when working with Excel files and CSV formats to avoid data corruption in MySQL databases?

When working with Excel files and CSV formats in PHP, developers should ensure that the character encoding is properly handled to avoid data corruption in MySQL databases. This can be achieved by setting the appropriate character encoding for reading and writing files, as well as specifying the correct encoding when interacting with the database. 

// Set character encoding for reading Excel files
ini_set('default_charset', 'UTF-8');

// Set character encoding for writing CSV files
header('Content-Type: text/csv; charset=utf-8');

// Specify character encoding for MySQL connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");
